Abstract: ABSTRACT OF THE DISCLOSURE          An improved method and system for mixing gas with waste water in which the water is pumped through a plurality of mixing chambers into which the gas is injected at a step region to form parallel streams of gas and water. An extending chamber contains the parallel streams as the interface between them becomes unstable, breaks down creating vortices and produces tiny bubbles which mix with the water. The extending chamber is tapered inwardly to permit opera-tion at higher air flow rates without blowing the bubble forming vortices out of the chamber.  Helical vanes are preferably provided in the bores which inject the air into the extending chamber to create better wave generating conditions to extend the range to greater air flow rates.

Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided for making diaryliodonium salt photoinitiators, based on the initial formation of a diaryliodonium bisulfate of the formula [(R)a (R1)b I]+ [HSO4]-where R is a monovalent aromatic organic radical selected from the class consisting of aromatic carbocyclic or heterocyclic having from 6-20 carbon atoms, R1 is a divalent aromatic organic radical, a is a whole number equal to 0  or 2, b is a whole number equal to 0 or 1, and the sum of a+b is equal to 1 or 2.  A significant improvement in reproducibility, reaction time and yield can be achieved in making diaryliodonium bisulfate salts if the acetic acid used in the reaction mixture of the previously-known method is replaced with methylene chloride and the reaction is run at a temperature of from -25°C to +25°C, preferably -5°C to +5°C.  The improved method for making bisulfate salts comprises:  A)  effecting a coupling reaction at a temperature of from -25°C to +25°C between a C(6-30) aromatic compound and potassium iodate in the presence of a mixture consisting essentially of methylene chloride, acetic anhydride and dulfuric acid, and B)  receiving the diaryliodonium bisulfate salt from the mixture of (A).      The bisulfate salt is reacted with a metal salt of the formula MQ to produce by a metathesis, a diaryliodonium salt of the formula [(R)a(R1)b I]+ Q-where M is a metal ion, Q is an anion selected from the class consisting of a halogen ion, YF6 , NO3-, C1O4 , CP3SO3-, PO4-3, SO4-2, HSO4 and CH3C6H5SO3-, and Y is selected from the class consisting of P, As and Sb. The resulting diaryliodonium salts can be used as photoinitiators which are useful in making ultraviolet-curnble compositions.

Abstract: ABSTRACT       Seed drill has a row of coulters which are raised and lowered by a beam extending along and above the row of coulters and connected to the coulters by spring assemblies.  The beam is raised and lowered relative to the frame of the drill by two rams to actuate the coulters.  The mounting of the beam comprises an articulated joint, such as a ball joint, which permits the ends of the beam to rise and fall independently of each other relative to the frame thereby permitting improved contour following by the coulters and avoiding excessive loads on the beam in the event of failure of one of the rams.

Abstract: ABSTRACT OF THE DISCLOSURE A bubble memory package is comprised of a nonmagnetizable heat sink formed with a pocket for receiving the field coil and magnetic chip carrier assemblies.  The heat sink is massive and capable of dissipating the heat generated by a high density memory operating at a high frequency.          The heat sink is not closed over the top of the coil and memory carrier assemblies to reduce eddy and circulating electrical currents formed in an electrically conductive heat sink.  The heat sink is formed with a track guide for receiving a heat sink plate which may be of electrically noncon-ductive material but which has sufficient heat conductivity to assist in transferring heat into the heat sink.  The top of the heat sink plate is formed with a pocket for receiving a permanent magnet to generate the bias field and the bottom of the heat sink is formed with a second pocket for receiving a magnet assembly.  The entire package is surrounded by a mag-netic shield container.

Abstract: ABSTRACT OF THE DISCLOSURE        An adjustless V-belt and method of manufacture.  The V-belt comprises: a compressive rubber layer made of a heat-proof or coldproof rubber and an adhesion rubber layer laminated on said compressive rubber layer.  A group of cogs protrude from said adhesion rubber layer with a predetermined pitch and depth and a longitudinally stretchable cover canvas covers the cogs, and the roots between said cogs.  Rope tensile members are embedded between the adhesion rubber layer and the group of cogs with a regular pitch line and in the cylindrical state such a manner that parts of the tensile members are in contact with said cover canvas.  The rope tensile members have a high thermal contraction stress of at least 3.5 g/denier which is the differential between a thermal contraction stress at 100°C and that at room temperature (about 20°C).  Short fibers are embedded in the compressive rubber layer in such a manner that the short fibers are orientated laterally therein.  A ply of rubberized canvas is bonded, in lamination, to the lower surface of the compressive rubber layer.  A reversal molding technique is used with the cover canvas first wound around a metal mold having protrusions and grooves followed by the rope tensile member, the adhesion rubber sheet, the compressive rubber sheet and finally the rubberized canvas.  A cylindrical sleeve is placed over the belt blank thus formed and the assembly is pressurized and heated to permit a portion of the adhesion rubber to fill the grooves in the metal mold.

Abstract: Abstract:      An expandable tire building drum has an improved bladder for expanding and contracting the drum segments. Instead of being a closed torus with a radially inwardly extending inflation stem, the bladder is completely open on its radially inward side and has beads that are clamped in an airtight seal to the bladder support.  The bladder in its deflated condition rests in three folded layers within its storage cavity in the drum.  This bladder con-struction allows a bladder having a relatively large surface area to be stored in a relatively small cavity. The space in the cavity for storing such bladders is often limited, particularly in drums for building radial passen-ger car tires.  Putting a larger bladder in this cavity than allowed by prior constructions results in a greater surface contact between the bladder and the drum segments when the bladder is inflated.  This enables the drum to be expanded using lower bladder pressures, which means the bladder walls do not have to be as strong and they will not wear out as fast.  Also, small air leaks is the bladder inflation system will not be as critical.

The light components are then, after being removed from the fiber, combined and compared with the signals applied at the input.  The phase difference therebetween is then established to measure the rate of rotation of the optical fiber about the axis of sensitivity.
